Are dental fillings painful?

Many types of fillings can indeed cause sensitivity in the tooth and aching in the jaw. If the pain doesn’t go away over time, see your dentist and get it checked out.

Tooth Pain Causes

If the tooth hurts after the filling procedure, it can be caused by one of the following reasons:

1. Malocclusion

A tooth that is positioned crooked or rotated needs to be rattled back into place. This is especially true for teeth that have root canal treatments. If fillings are not positioned right, it could hurt your teeth and affect how you bite. The dentist can adjust the fill to correct your bite.

2. Filling Type

The type of material used, the design, and the way it is positioned can all affect the level of sensitivity. Some materials are more sensitive; for example, gold is harder and can cause more pain. Proper shaping to cover the cavity is essential to prevent sensitivity with composite fillings.

You might find that the filling is not what you thought it would be. Composite resin can shrink slightly over time, creating a space between your teeth and the filling, which can lead to sensitivity.

How the filling is positioned in the tooth is essential for preventing sensitivity and pain. If the filling does not fit snugly, it can cause pain.

3. Exposed Pulp

The pulp can be exposed when the filling is removed. The nerve in your teeth can be aggravated as well. A root canal is your best option if this is the cause of your discomfort after the filling procedure.

The best thing to do is to visit the dentist. They have the best solutions for this problem because they have experience and information on how to help you treat it. Also, keeping up with your oral hygiene is a good idea because it will help you avoid more cavities.

Jaw Pain Causes

Jaw pain after the filling procedure may be caused by:

1. Jagged Filling

When your jaw hurts, the culprit might be a tooth filling. If it’s not that, something else could be causing the pain. However, some fillings are known to cause jaw pain.

2. Keeping the Jaw Open

The pain in my jaw that I’m experiencing right now is a side effect of keeping my mouth open for an extended period during the procedure. You will get used to it in time.

When Should You Call Your Dentist?

If your toothache persists after a few days, and you have already tried the home remedies to no avail, you should probably call your dentist and make an appointment.

In the meantime, the best thing you can do is to keep the tooth as clean as possible. Use warm salt water and gently brush it with a soft-bristled toothbrush. Do not use a hard or sharp object to clean the tooth because it could damage your filling. Eat soft foods, cause hard foods and liquids can irritate your teeth.


In conclusion, several reasons can cause toothaches after your filling procedure. The dentist will get the filling right after seeing what is causing the pain. You don’t have to suffer. If you have any of the signs and symptoms, see your dentist and get it checked out.
